MISSOURI MUNICIPAL WATER POLLUTION PREVENTION SURVEY
What is the Missouri Water Pollution Prevention Survey?The Missouri Municipal Water Pollution Prevention Survey (MWPP) is an annualself-evaluation of your sewer utility. The MWPP is a tool for management and operationspersonnel to jointly evaluate the wastewater utility system. The survey will help identify systemstrengths and weaknesses. You can use this information to plan system improvements orupgrades, and operational or financial changes. These improvements will help you maintaincompliance with your National Pollutant Discharge Elimination System (NPDES) dischargepermit.
The survey is divided into five sections:
The Wastewater Utility Systems section identifies the various components of yourutility system and addresses operation and maintenance issues.
The Loading / Capacity section examines the hydraulic and organic loads on the system,compares the loading to design capacity, and looks at the treatment efficiency of thesystem.
The Sludge and Biosolids-Disposal and Reuse section identifies the sludge managementsystems and evaluates adherence to “503” sludge regulations.
The Sewer Use section evaluates the sewer use ordinance and the effects of localcommercial and industrial facilities on the wastewater treatment system.
The Management and Financial Capacity section examines the ability of themanagement and financial systems to provide for the long-term viability of the utility.
The MWPP Survey is available in three forms:• You can request a paper form from the Missouri Department of Natural Resources’
Technical Assistance Program.• You can access the MWPP Survey in pdf format at our web site and print it on paper
yourself (http://www.dnr.state.mo.us/deq/tap/pubs.htm, Water Pollution Control, MO 780-1559).
• You can download the Microsoft Word template from our web site and complete thesurvey electronically (http://www.dnr.state.mo.us/deq/tap/emiapps.htm, Downloadthe EMI Software,)

To complete the MWPP Survey electronically, follow these steps:• Download the files (files will be placed on your C: drive in a subdirectory called
EMI).• Open the file MWPPSurv in Word.• Save the form under a new name (this way you will have the original blank template
if needed).• Enter information in highlighted blanks. Mark check boxes by clicking on them.
Calculations are performed automatically as the required figures are input.• To move from field to field, use the arrow keys or the tab key.• To move to a particular page, use the right scroll bar or the mouse scroll wheel.
The form is a template. If you wish to modify the form to fit special needs of your system, referto the instructions for customization at the end of the survey.
What resources will I need to complete the survey?• NPDES permit• Discharge monitoring reports• Operations and maintenance manual• Utility financial reports• Internet connection to download the pdf form or Word template *• MS Word to fill in the template form electronically *
* not required for manual completion of form
What do I do if our system has more than one treatment facility?The MWPP Survey form covers one treatment facility. If you have additional wastewatertreatment facilities, fill out the form “Additional Facilities” for each one. If you are filling outyour form electronically, open the file MWPPAdd, located on the C: drive in the EMIsubdirectory.
Do I have to participate in the MWPP Survey Program?No! Participation in the MWPP survey is voluntary. We developed the MWPP Survey as atool for you to use to assess the technical, managerial, and financial capacity of your wastewatersystems. It will give you a snapshot of your system’s health and that is reason enough to use thetool.
However, Missouri State Regulation 10 CSR 20-9 (7) gives you some incentive to complete andreturn the form. If you should run into compliance problems and you have participated in thesurvey for previous five consecutive years, the regulation provides for additional “conference andconciliation” communications and penalty reductions. In essence, completing the form regularlyis a demonstration of your intent to manage your wastewater systems properly and we want torecognize you for that.

16MO 780-1559 (5-01)
Operating Ratio:
If you check the operating ratio every month and compare it to past values, it will show thetrend of your utility finances. The trend should be steady or upward. If the operating ratio is overthe minimum value required to pay all the bills and it is holding steady, your utility is probablyfinancially healthy. If the ratio is below the minimum value or falling, you need to do somethingto get it back in shape. Think of the operating ratio as the pulse of the utility.
To calculate your operating ratio, divide total revenues by the total operating expenses. Year–to-date financial data is used in the calculations. Year-to-date financial data is the total of the mostrecent 12 months of financial data. For example, to calculate the operating ratio as of June 30,2000, you would use the financial data from July 1, 1999 through June 30, 2000.
Our Total Revenues year-to-date are $ . (Includes user charge fees, penalty payments, impact fees, hookup fees, tax assessments,interest income and any other revenue.)
Our Total Operating Expenses year-to-date are $ .(Includes administration, wages, benefits, taxes, insurance, utilities, chemicals, supplies,professional services, reserve account deposits, existing principal and interest paymentsand any other expenses.)
Our Operating Ratio = Total Revenue = . Total Operating Expenses
(The bare minimum operating ratio for a self-sustaining system is 1.00. If yours is less,you need to take steps to balance your expenses and revenues immediately! The operatingratio for most systems should exceed 1.15; small systems may need an operating ratio of1.50.)
We check our operating ratio monthly and compare it to past values.
Coverage Ratio:
The Coverage Ratio measures whether your utility has enough revenue to pay the principal andinterest on its loans or bonds. Calculate the Coverage Ratio if your system has debt service.
Our annual Debt Service Expenses (principal & interest) = $ .
Our Non-Debt Expenses (Total Operating Expenses - Debt Service Expenses) = $ .
Our Revenue Available for Debt Service (Total Revenue - Non-Debt Expenses) = $ .
Our Coverage Ratio = Revenue Available for Debt Service = Debt Service Expenses
We check our coverage ratio at least quarterly and compare it to past values.
17MO 780-1559 (5-01)
Our coverage ratio meets the requirements of our outstanding bonds and loans.(Usually the terms of a bond or loan require a coverage ratio of 1.25 or higher.)
User Charge:
Having an adequate user charge in place is essential for operating and maintaining yourwastewater utility.
We have a user charge ordinance in place.
We review our user charge rates at least once every two years and adjust rates as needed.
Our rate structure is fair and equitable.
The operation and maintenance costs of our system are charged to customers on a“proportional to use” basis (required for EPA grant and SRF loan recipients).
We have surcharges for high-strength or high-volume wastewater flows released into thesewage system (if there are such discharges).
We keep our customers well informed of the rate structure.
The number of customers connected to our system, including those we do not charge = .
The number of customers who regularly pay their bills every month = .
Our collection rate = # of customer accounts collected X 100 = %. total number of customer accounts
(If the collection rate is less than 95%, you should take steps to improve collections.)
Average Treatment Costs:
Our average cost to treat 1000 gallons of wastewater =
Total Operating Expenses per year x 1000 gallons = $ per 1000 gal.(Average Daily Flow gal/day) x (365 days/yr.)
We calculate our average treatment costs/1000 gallons each year and compare this figureto past values.
Our treatment costs/1000 gallons have remained stable or risen at a manageable rate overthe past year.

The design average hydraulic capacity of our system is MGD.
Ninety percent of the design hydraulic capacity is MGD (MGDx.90).
The average daily flow (Table 1 col. 4) exceeded 90 percent of the design hydraulic capacity times last year.
The peak hydraulic capacity of our system is MGD.
The highest peak flow (Table 1 col. 3) exceeded the peak hydraulic capacity of our system times last year.
The design average organic capacity of our system is BOD lbs./day.
Ninety percent of the design average organic capacity is BOD lbs./day (BODx.90).
The average daily organic loading (Table 1 col. 6) exceeded 90 percent of the design averageorganic capacity times last year. There were bypasses (Table 1 col. 2) due to storm water last year.
There were bypasses (column 2) due to equipment failure last year.
Our treatment facility has significant seasonal fluctuations in loading due to population orwater use variations (e.g., students, tourism, institutional populations, industrial water usevariations, migrant workers, part-year residents).

II. GROWTH AND EXPANSION
Check those boxes that apply to your facility.
The design population equivalent for our system is .
The current population equivalent served by our system is estimated to be .
Over the next 5 years, we anticipate that our community’s population will:
Grow significantly.
Remain about the same.
Decline significantly.
Over the next 5 years, we anticipate that our community will:
Extend sewer service to previously unsewered areas of the community.
See significant new residential development.
See significant new commercial development.
See a significant decrease in commercial facilities.
See significant new industrial development.
See a significant decrease in industrial operations.
We believe that these changes will:
Not require any operational or physical changes to the treatment facility.
Require operational changes at the treatment facility.
Require a treatment facility upgrade.
Require a treatment facility expansion.
